滨海火电厂循环水管道中硫化氢等有毒有害气体的积累不仅会影响冷却系统的正常运行，还会对周边环境及现场作业人员的健康造成严重危害，是困扰火电厂安全运行的重大难题.因此，研究火电厂循环水管道中硫化氢的产生机制并针对性提出防控措施，是火电厂亟需解决的科学问题.基于此，本文从滨海火电厂循环水管道中如何产生硫化氢及防治的科学问题出发，介绍了硫化氢对环境、设备和人员的严重危害，综述了不同自然环境中硫化氢产生的机制，指出了微生物介导硫酸盐还原作用是循环水管道中硫化氢产生的关键，并根据国内外研究进展对硫化氢的防治策略进行了展望.本文对于科学防控火电厂循环水管道产生硫化氢等有毒有害气体的风险具有重要的指导意义.
Abstract：The accumulation of toxic and harmful gases such as hydrogen sulfide in the circulating water pipelines of coastal thermal power plants not only affects the normal operation of the cooling system, but also poses a serious threat to the surrounding environment and the health of on-site workers, which is a major challenge to the safe operation of coastal thermal power plants. Therefore,studying the mechanism of hydrogen sulfide production in the circulating water pipelines of coastal thermal power plants and proposing specific preventive measures are the scientific issues that urgently need to be addressed. According to the scientific problem that how hydrogen sulfide is produced and its prevention and control, this article introduces the serious harm of hydrogen sulfide to the environment, equipment, and on-site workers, and summarizes the mechanism of hydrogen sulfide production in the different types of natural environment. Then, this article points out the microbially mediated sulfate reduction that is the dominant factor to the production of hydrogen sulfide in the circulating water pipelines, and looks forward to the prevention and control measures of hydrogen sulfide based on the domestic and foreign research progress. This article has important guiding significance for the risk prevention and control of toxic and harmful gases such as hydrogen sulfide generated in the circulating water pipelines of coastal thermal power plants.
